前言

1.由于粘贴了较大的代码，造成内容比较长，可能会花费您较长的时间。
2.项目里面没有做权限判断，所以如果发现有页面发生崩溃可能是权限没有打开，请打开权限后再进行尝试。
3.录制的GIF画质好差，真实环境很好。

一.有图有真相

游客端 :　/uploadfile/2016/0902/20160902091910582.gif

二.集成步骤，教你实现直播连麦互动

从github上https://github.com/AnyRTC/RTMPCHybirdEngine-Android下载下来，导入AS，结构如下图所示。

1.初始化RTMP引擎

MainActivity.java

RTMPCHybird.Inst().Init(getApplicationContext());
 RTMPCHybird.Inst().InitEngineWithAnyrtcInfo("你的开发者ID", "liveDemo", "LslMfUyvcW8hv6NgY0n8FOWf5t1K+YWpoMzRsqwkBiE", "d6ff4b7d1b549f497a0b94cf500fd549");

以上的四个参数可以在https://www.anyrtc.io注册开发者账号并创建一个应用可得，如下图所示。你可以把它放在继承Application的onCreate()方法中。

2.获取直播列表，随时随地观看主播

MainActivity.java

RTMPCHttpSDK.GetLiveList(this, RTMPCHybird.Inst().GetHttpAddr(), 你的开发者ID", "liveDemo",     "d6ff4b7d1b549f497a0b94cf500fd549", mRTMPCHttpCallback);

    private RTMPCHttpSDK.RTMPCHttpCallback mRTMPCHttpCallback = new RTMPCHttpSDK.RTMPCHttpCallback() {
        @Override
        public void OnRTMPCHttpOK(String strContent) {
            mRecyclerViewUtils.endRefreshing();
            try {
                listLive.clear();
                JSONObject liveJson = new JSONObject(strContent);
                JSONArray liveList = liveJson.getJSONArray("LiveList");
                JSONArray memberList = liveJson.getJSONArray("LiveMembers");
                for (int i = 0; i < liveList.length(); i++) {
                    LiveItemBean bean = new LiveItemBean();
                    JSONObject itemJson = new JSONObject(liveList.getString(i));
                    bean.setmHosterId(itemJson.getString("hosterId"));
                    bean.setmRtmpPullUrl(itemJson.getString("rtmp_url"));
                    bean.setmHlsUrl(itemJson.getString("hls_url"));
                    bean.setmLiveTopic(itemJson.getString("topic"));
                    bean.setmAnyrtcId(itemJson.getString("anyrtcId"));
                    bean.setmMemNumber(memberList.getInt(i));
                    listLive.add(bean);
                }
                mAdapter.setDatas(listLive);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void OnRTMPCHttpFailed(int code) {

        }
    };

以上代码可以获取所有正在直播列表名单

3.发起直播，成就自己的直播梦

a.你可以自己设置推流地址和拉流地址，这里我直接用他提供的地址了

RTMPUrlHelper.java

public class RTMPUrlHelper {
    /**
     * rtmp 推流地址
     */
    public static final String RTMP_PUSH_URL = "rtmp://192.168.7.207:1935/live/%s";
    /**
     * rtmp 拉流地址
     */
    public static final String RTMP_PULL_URL = "rtmp://192.168.7.207:1935/live/%s";
    /**
     * hls 地址
     */
    public static final String HLS_URL = "http://192.169.7.207/live/%s.m3u8";
    /**
     * 分享页面url地址
     */
    public static final String SHARE_WEB_URL = "http://123.59.68.21/rtmpc-demo/?%s";
}

b.这里要使用到你创建应用的anyrtcid、推流拉流hls地址、直播名称。到这一步你已经离你的直播梦完成了一半了<(￣︶￣)>。

PreStartLiveActivity.java

String anyrtcId = RTMPCHttpSDK.getRandomString(12);
            String rtmpPushUrl = String.format(RTMPUrlHelper.RTMP_PUSH_URL, anyrtcId);
            String rtmpPullUrl = String.format(RTMPUrlHelper.RTMP_PULL_URL, anyrtcId);
            String hlsUrl = String.format(RTMPUrlHelper.HLS_URL, anyrtcId);
            JSONObject item = new JSONObject();
            try {
                item.put("hosterId", "hostID");
                item.put("rtmp_url", rtmpPullUrl);
                item.put("hls_url", hlsUrl);
                item.put("topic", topic);
                item.put("anyrtcId", anyrtcId);
            } catch (JSONException e) {
                e.printStackTrace();
            }
            Bundle bundle = new Bundle();
            bundle.putString("hosterId", "hostID");
            bundle.putString("rtmp_url", rtmpPushUrl);
            bundle.putString("hls_url", hlsUrl);
            bundle.putString("topic", topic);
            bundle.putString("andyrtcId", anyrtcId);
            bundle.putString("userData", item.toString());
            Intent intent = new Intent(this, HosterActivity.class);
            intent.putExtras(bundle);
            startActivity(intent);

4.你的直播梦就在此就要实现了，打起精神(⊙o⊙)哦

a.从上个Activity拿到传过来的数据

HosterActivity.java

 mHosterId = getIntent().getExtras().getString("hosterId");
        mRtmpPushUrl = getIntent().getExtras().getString("rtmp_url");
        mAnyrtcId = getIntent().getExtras().getString("andyrtcId");
        mUserData = getIntent().getExtras().getString("userData");
        mHlsUrl = getIntent().getExtras().getString("hls_url");
        mTopic = getIntent().getExtras().getString("topic");

这里的R.id.rl_rtmpc_videos表示打开手机摄像头捕获的像呈现的地方，如下图所示。
HosterActivity.java

mVideoView = new RTMPCVideoView((RelativeLayout) findViewById(R.id.rl_rtmpc_videos), RTMPCHybird.Inst().Egl(), true);
        mVideoView.setBtnCloseEvent(mBtnVideoCloseEvent);
        mHosterKit = new RTMPCHosterKit(this, mHosterListener);

        {
            VideoRenderer render = mVideoView.OnRtcOpenLocalRender();
            mHosterKit.SetVideoCapturer(render.GetRenderPointer(), true);
        }

b.这里是创建和音频管理器，将照顾音频路由，音频模式，音频设备枚举等、存储现有的音频设置更改音频模式达到最佳的VoIP性能。

           {
            // Create and audio manager that will take care of audio routing,
            // audio modes, audio device enumeration etc.
            mRtmpAudioManager = RTMPAudioManager.create(this, new Runnable() {
                // This method will be called each time the audio state (number
                // and
                // type of devices) has been changed.
                @Override
                public void run() {
                    onAudioManagerChangedState();
                }
            });
            // Store existing audio settings and change audio mode to
            // MODE_IN_COMMUNICATION for best possible VoIP performance.
            mRtmpAudioManager.init();
            mRtmpAudioManager.setAudioDevice(RTMPAudioManager.AudioDevice.SPEAKER_PHONE);
        }

        mStartRtmp = true;
        /**
         * 开始推流
         */
        mHosterKit.StartPushRtmpStream(mRtmpPushUrl);
        /**
         * 建立RTC连线连接
         */
        mHosterKit.OpenRTCLine(mAnyrtcId, mHosterId, mUserData);

c.主播的直播回调接口

mHosterKit = new RTMPCHosterKit(this, mHosterListener);
这句代码是主播直播的回调接口，可以做连麦、取消连麦、接收消息和弹幕消息、实时观看人数和人员上下线等。实用的操作一般再此实行。
HosterActivity.java

/**
     * 主播回调信息接口
     */
    private RTMPCAbstractHoster mHosterListener = new RTMPCAbstractHoster() {
        /**
         * rtmp连接成功
         */
        @Override
        public void OnRtmpStreamOKCallback() {
            HosterActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ((TextView) findViewById(R.id.txt_rtmp_connection_status)).setText(R.string.str_rtmp_connect_success);
                }
            });
        }

        /**
         * rtmp 重连次数
         * @param times 重连次数
         */
        @Override
        public void OnRtmpStreamReconnectingCallback(final int times) {
            HosterActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ((TextView) findViewById(R.id.txt_rtmp_connection_status)).setText(String.format(getString(R.string.str_reconnect_times), times));
                }
            });
        }

        /**
         * rtmp 推流状态
         * @param delayMs 推流延时
         * @param netBand 推流码流
         */
        @Override
        public void OnRtmpStreamStatusCallback(final int delayMs, final int netBand) {
            HosterActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ((TextView) findViewById(R.id.txt_rtmp_status)).setText(String.format(getString(R.string.str_rtmp_status), delayMs, netBand));
                }
            });
        }

        /**
         * rtmp推流失败回调
         * @param code
         */
        @Override
        public void OnRtmpStreamFailedCallback(int code) {
            HosterActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ((TextView) findViewById(R.id.txt_rtmp_connection_status)).setTextColor(R.color.yellow);
                    ((TextView) findViewById(R.id.txt_rtmp_connection_status)).setText(R.string.str_rtmp_connect_failed);
                }
            });
        }

        /**
         * rtmp 推流关闭回调
         */
        @Override
        public void OnRtmpStreamClosedCallback() {
            finish();
        }

        /**
         * RTC 连接回调
         * @param code 0： 连接成功
         * @param strErr 原因
         */
        @Override
        public void OnRTCOpenLineResultCallback(final int code, String strErr) {
            HosterActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    if (code == 0) {
                        ((TextView) findViewById(R.id.txt_rtc_connection_status)).setText(R.string.str_rtc_connect_success);
                    } else {
                        ((TextView) findViewById(R.id.txt_rtc_connection_status)).setTextColor(R.color.yellow);
                        ((TextView) findViewById(R.id.txt_rtc_connection_status)).setText(R.string.str_rtmp_connect_failed);
                    }
                }
            });
        }

        }
    };

d.一些对应直播回调的方法

接下来就要说对应这些回调的方法了，这里可以做关闭直播、直播分享、切换摄像头和发送消息。
HosterActivity.java

public void OnBtnClicked(View btn) {
        if (btn.getId() == R.id.btn_close) {
            mStartRtmp = false;
            mHosterKit.StopRtmpStream();
            finish();
        } else if (btn.getId() == R.id.btn_copy_hls) {
            int index = mHlsUrl.lastIndexOf("/");
            int lastIndex = mHlsUrl.lastIndexOf(".");
            String shareUrl = String.format(RTMPUrlHelper.SHARE_WEB_URL, mHlsUrl.substring(index + 1, lastIndex));
            mShareHelper.shareWeiXin(mTopic, shareUrl);
        } else if (btn.getId() == R.id.btn_switch_camera) {
            mHosterKit.SwitchCamera();
        } else if (btn.getId() == R.id.btn_send_message) {
            String message = editMessage.getText().toString();
            editMessage.setText("");
            if (message.equals("")) {
                return;
            }
            if (mCheckBarrage.isChecked()) {
                mHosterKit.SendBarrage(mNickname, "", message);
                IDanmakuItem item = new DanmakuItem(HosterActivity.this, new SpannableString(message), mDanmakuView.getWidth(), 0, R.color.yellow_normol, 18, 1);
                mDanmakuView.addItemToHead(item);
            } else {
                mHosterKit.SendUserMsg(mNickname, "", message);
            }

            addChatMessageList(new ChatMessageBean(mNickname, mNickname, "", message));
        } else if (btn.getId() == R.id.iv_host_text) {
            btnChat.clearFocus();
            vaBottomBar.setDisplayedChild(1);
            editMessage.requestFocus();
            softKeyboardUtil.showKeyboard(HosterActivity.this, editMessage);
        }
    }

5.主播端的已经完成了，现在该轮到你的小伙伴们看你直播~(≧▽≦)/~啦啦啦

a.前面已经说了，我们可以实时获取开启直播的主播，点击列表就可以观看主播直播。

MainActivity.java

@Override
    public void onItemChildClick(ViewGroup viewGroup, View view, int i) {
        Intent it = new Intent(this, GuestActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("hls_url", listLive.get(i).getmHlsUrl());
        bundle.putString("rtmp_url", listLive.get(i).getmRtmpPullUrl());
        bundle.putString("anyrtcId", listLive.get(i).getmAnyrtcId());
        bundle.putString("userData", new JSONObject().toString());
        bundle.putString("topic", listLive.get(i).getmLiveTopic());
        it.putExtras(bundle);
        startActivity(it);
    }

b.再实现游客端这个项目基本上就完成了，是不是有点小激动？

与主播端一样，拿上个Activity传过来的数据，其实这里代码与主播端的代码基本上可以说是一模一样，看完之后你应该会有我这样的体会。
GuestActivity.java

mNickname = ((HybirdApplication)HybirdApplication.app()).getmNickname();
        mRtmpPullUrl = getIntent().getExtras().getString("rtmp_url");
        mAnyrtcId = getIntent().getExtras().getString("anyrtcId");
        mHlsUrl = getIntent().getExtras().getString("hls_url");
        mGuestId = mNickname;//getIntent().getExtras().getString("guestId");

        mTopic = getIntent().getExtras().getString("topic");

mVideoView = new RTMPCVideoView((RelativeLayout) findViewById(R.id.rl_rtmpc_videos), RTMPCHybird.Inst().Egl(), false);

        mVideoView.setBtnCloseEvent(mBtnVideoCloseEvent);
        /**
         * 初始化rtmp播放器
         */
        mGuestKit = new RTMPCGuestKit(this, mGuestListener);
        VideoRenderer render = mVideoView.OnRtcOpenLocalRender();

        {
            // Create and audio manager that will take care of audio routing,
            // audio modes, audio device enumeration etc.
            mRtmpAudioManager = RTMPAudioManager.create(this, new Runnable() {
                // This method will be called each time the audio state (number
                // and
                // type of devices) has been changed.
                @Override
                public void run() {
                    onAudioManagerChangedState();
                }
            });
            // Store existing audio settings and change audio mode to
            // MODE_IN_COMMUNICATION for best possible VoIP performance.
            mRtmpAudioManager.init();
            mRtmpAudioManager.setAudioDevice(RTMPAudioManager.AudioDevice.SPEAKER_PHONE);
        }

        mUserData = new JSONObject();
        try {
            mUserData.put("nickName", mNickname);
            mUserData.put("headUrl", "");
        } catch (JSONException e) {
            e.printStackTrace();
        }

        /**
         * 开始播放rtmp流
         */
        mGuestKit.StartRtmpPlay(mRtmpPullUrl, render.GetRenderPointer());
        /**
         * 开启RTC连线连接
         */
        mGuestKit.JoinRTCLine(mAnyrtcId, mGuestId, mUserData.toString());

c.观看直播的回调接口

mGuestKit = new RTMPCGuestKit(this, mGuestListener);
这句代码是观看直播的回调接口，可以做申请连麦、断开连麦、接收消息和弹幕消息、实时观看人数和人员上下线等。实用的操作一般再此实行。
GuestActivity.java

/**
     * 观看直播回调信息接口
     */
    private RTMPCAbstractGuest mGuestListener = new RTMPCAbstractGuest() {

        /**
         * rtmp 连接成功
         */
        @Override
        public void OnRtmplayerOKCallback() {
        }

        /**
         * rtmp 当前播放状态
         * @param cacheTime 当前缓存时间
         * @param curBitrate 当前播放器码流
         */
        @Override
        public void OnRtmplayerStatusCallback(int cacheTime, int curBitrate) {

        }

        /**
         * rtmp 播放缓冲区时长
         * @param time 缓冲时间
         */
        @Override
        public void OnRtmplayerCacheCallback(int time) {

        }

        /**
         * rtmp 播放器关闭
         * @param errcode
         */
        @Override
        public void OnRtmplayerClosedCallback(int errcode) {

        }

        /**
         * 游客RTC 状态回调
         * @param code 回调响应码：0：正常；101：主播未开启直播；

        @Override
        public void OnRTCJoinLineResultCallback(final int code, String strReason) {
            GuestActivity.this.runOnUiThread(new Runnable() {

                public void run() {
                    if (code == 0) {

                    } else if (code == 101) {
                        Toast.makeText(GuestActivity.this, R.string.str_hoster_not_live, Toast.LENGTH_LONG).show();
                        mHandler.sendEmptyMessageDelayed(CLOSED, 2000);
                    }
                }
            });
        }

        /**
         * 游客申请连线回调
         * @param code 0：申请连线成功；-1：主播拒绝连线
         */
        @Override
        public void OnRTCApplyLineResultCallback(final int code) {
            GuestActivity.this.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    if (code == 0) {
                        VideoRenderer render = mVideoView.OnRtcOpenRemoteRender("LocalCameraRender");
                        mGuestKit.SetVideoCapturer(render.GetRenderPointer(), true);
